Constellation Energy (CEG) is set to release its first-quarter 2026 earnings on Monday, May 11, at 10 a.m. EDT, with investors closely watching for updates on the company's AI-fueled power strategy and its recent acquisition of Calpine. The stock closed Friday at $303.63, down 6% from Wednesday's $322.78, as traders reduced positions ahead of the report. Options pricing suggests a potential 7% swing in the stock price following the earnings release, according to Investopedia.
Analysts polled by Visible Alpha forecast adjusted earnings of $2.34 per share on revenue of $8.66 billion for the quarter. The results come amid heightened interest in nuclear and natural gas power as tech giants like Microsoft and Meta seek reliable electricity to power their expanding data center networks, which are increasingly strained by AI workloads.
Calpine Integration and 2026 Outlook
This earnings report is a key early test following Constellation's acquisition of Calpine in January, a deal that the company says makes it the largest electricity producer in the U.S. The combined entity now operates approximately 55 gigawatts of capacity, blending Calpine's natural gas and geothermal assets with Constellation's nuclear portfolio. Constellation has set a 2026 adjusted operating earnings target of $11 to $12 per share, with growth capital spending planned at $3.9 billion and a $5 billion share buyback program in place.
Management's commentary on the Calpine integration, plant outages, hedging activities, cash flow, and the pace of long-term power purchase agreements will be critical. If the company reaffirms its 2026 guidance, it could help stabilize the stock. However, any delays in grid approvals or softer language on new contracts may prompt investors to hold back.
Three Mile Island Restart and Regulatory Hurdles
A major focal point is the planned restart of the former Three Mile Island nuclear unit, now rebranded as the Crane Clean Energy Center. The facility is intended to supply power to Microsoft's data centers, but PJM Interconnection, the grid operator for much of the Mid-Atlantic and Midwest, has flagged the possibility that the grid connection could slip to 2031. Constellation CEO Joseph Dominguez has maintained that the company expects to restart the unit in 2027, stating, "We are working on that with PJM, and we continue to expect to start this unit in 2027." Analysts at Melius Research have emphasized that clarity from PJM remains a key catalyst for the stock.
UBS analyst William Appicelli recently lowered his price target on Constellation to $388 from $420 while maintaining a Buy rating, citing overhangs such as uncertainty around PJM, regulatory clarity from the Federal Energy Regulatory Commission (FERC), and looming share lockup expirations.
Mixed Signals from Rivals
Earnings reports from peers have offered a mixed picture. Vistra posted a quarterly profit this week, reversing a year-ago loss as power demand and prices climbed. NRG Energy, however, fell short of quarterly profit expectations due to mild Texas weather and rising costs. Exelon raised its capital spending outlook, pointing to increased utility budgets as tech firms ramp up data center construction. These developments underscore that while demand for electricity remains robust, the sector faces headwinds from weather, fuel costs, financing, and execution risks.
For Constellation, the earnings call will provide insight into how the company is navigating these dynamics. The focus will be on whether the AI-driven power demand narrative is translating into tangible financial results, or if the stock's recent decline reflects skepticism about the pace of execution. Investors will also look for updates on the pace of new long-term power deals and the company's ability to manage its 55-gigawatt portfolio effectively.
